Cotton

Cotton is a soft, fluffy fiber that grows around the seeds of the cotton plant. It is one of the most important cash crops used worldwide in the textile industry, for products like clothing, towels, and more.

Cultivation and Growth

Associated Diseases

Cotton Wilt

Cotton wilt is caused by fungi such as Verticillium dahliae or Fusarium oxysporum. These fungi invade the plant's vascular system, blocking the flow of water and nutrients.

Cotton Wilt Disease

Prevention:

  • Plant disease-resistant varieties of cotton.
  • Rotate crops with non-host plants like maize or sorghum.
  • Maintain good drainage to prevent waterlogging.
  • Use certified, disease-free seeds.

Verticillium Wilt

This disease causes leaf curling and wilting due to fungal infection in the vascular tissues.

Verticillium Wilt Disease

Prevention:

  • Choose resistant cotton varieties.
  • Practice crop rotation with non-susceptible crops.
  • Ensure proper soil drainage and avoid over-irrigation.

Bacterial Blight

Bacterial blight causes lesions on leaves and bolls, leading to defoliation and crop loss.

Bacterial Blight Disease

Prevention:

  • Use disease-free seeds and resistant varieties.
  • Avoid overhead irrigation to prevent water splashing.
  • Sanitize tools and equipment to avoid contamination.

Anthracnose

This fungal disease causes dark, sunken lesions on bolls and leaves, leading to premature shedding and crop loss.

Anthracnose Disease

Prevention:

  • Use certified, disease-free seeds.
  • Practice crop rotation to reduce disease pressure.
  • Fungicide applications may help reduce infections.

Root Rot

This disease affects the roots of cotton plants, causing wilting and yellowing of leaves.

Root Rot Disease

Prevention:

  • Improve soil drainage to avoid water buildup.
  • Use fungicide-treated seeds.
  • Avoid planting cotton in waterlogged soils.

Alternaria Leaf Spot

This fungal disease causes small, circular dark spots on leaves, which can lead to defoliation.

Alternaria Leaf Spot Disease

Prevention:

  • Apply fungicides as needed to control the spread.
  • Ensure good air circulation around plants by proper spacing.
  • Remove infected plant debris from the field to reduce spread.
